Texas Wintering Waterfowl

Do you know how to identify all the waterfowl you see on our local ponds and lakes this winter? If not, I will be offering a 2 hour class on identifying those waterfowl. The species we will focus on are Swans, Geese, Ducks, Mergansers, Loons, Grebes & Cormorants. There is no charge for this class, however, donations to cover the rental of our classroom is appreciated.
